Abstract

The high-pressure gas discharge lamp according to the invention has electrodes comprising a rod of mainly tungsten and a helical winding of mainly tungsten near the tip of the rod. The winding has a first layer of turns, which is integral with a second layer of turns. The turns of the second layer are wound with torsion in the wire and surround turns of the first layer which are also wound with torsion. The direction of the torsion in a turn is equal to the direction in which the turn extends around the rod. As a result, the turns with torsion surround with tight fit their substrate and the winding is securely fixed ot the electrode rod.
